how to restart plugin after subprocess exited

[lzytaro]

helo, i'm studing go-plugin. i want to know how to restart plugin procee after killed plugin process or plugin process exit unexpected.

	// Request the plugin
	raw, err := rpcClient.Dispense("greeter")
	if err != nil {
		log.Fatal(err)
	}

	// We should have a Greeter now! This feels like a normal interface
	// implementation but is in fact over an RPC connection.
	greeter := raw.(shared.Greeter)
	fmt.Println(greeter.Greet())
	for {
        // killed plugin process while ranging
		if client.Exited() {
			log.Println("plugin exited")
			fmt.Println(client.Start())    // here print: 127.0.0.1:10001 <nil> ; but sub process doesn't started
		}
		time.Sleep(time.Second * 1)
	}
